Safety First Always observe safety precautions when using any electrical appliance.
Read these instructions carefully and retain them for future reference.
When the appliance is used by or near young children or infirm persons,
close supervision is necessary, especially to ensure children do not play
with it.
Do not use this appliance for other than its intended use.
Do not cover the grilles or block the entry or exhaust of airflow by
placing objects up against the refrigeration freezer unit.
Do not probe any opening.
Only use this appliance with the voltage specified on the cabinet rating
label affixed to the refrigeration unit.
Ensure the freezer has adequate ventilation as this is essential to
economical, high performance.
Be careful not to touch moving parts and hot surfaces.
For your own safety and that of others, ensure that all electrical work is
done by authorised personnel.
If the power supply flexible cord becomes damaged, it must be replaced
by an authorised service agent or similarly qualified person in order to
avoid a hazard.
Ensure all necessary safety precautions are observed during installation
or removal of the refrigeration unit.
The freezer is not designed to be stable while in motion. Use extreme
caution when moving or transporting the freezer.
WARNING
The TMEF1500 (3 door) freezer has two seperate power
supplies.
CAUTION
Always isolate the cabinet from the power supply before
attempting any maintenance.
CAUTION
Never overload the power supply, which could damage the
chiller and product. See the rating label inside the cabinet for
the safe power supply and current draw.

User Manual
Positioning the Cabinet
Before
Operating Follow the below steps to ensure the back sign panel is reversed and the
rear spacer is protruding from the back of the cabinet (TMEF1500 3 door
cabinet only). This will provide the necessary air gap at the rear of the
cabinet for correct operation.
1. Cut the cable ties securing the sign back panel to the sign side panels.
2. Reverse the sign back panel so that the rear spacer protrudes from the
rear of the cabinet, and attach the sign back panel to the cabinet by
hooking into the slots on the sign side panel ends.
3. Retrieve and unravel the power cords and fit through the exit holes on
top of the rear spacer.
Power Cord The freezer has a flexible power cord fitted with a 3-pin plug, which exits
from the top rear of the cabinet. Pull the power cord around so that it’s not
trapped before you position the cabinet.
Note: The TMEF1500 (3 door) freezer has two power cords, one for each
refrigeration unit.
Cabinet
Location The location of the freezer may be the single most important decision that
will extend its life and ensure economical, high performance. We
recommend that you put the freezer in the coolest place possible because it
will use less power and last longer.
Avoid direct sunlight, warm draughts etc. Allow adequate space for doors to
open and close properly. Self-closing doors have internal torsion bars
pretensioned at the factory, and must be unobstructed. Ensure the cabinet
sits on a level surface so that the doors shut and correctly seal. Level footing
also prevents the condensate tray from overflowing.

Ventilation Adequate ventilation is essential:
Ensure the is a minimum of 200mm of space above the cabinet and
100mm behind the cabinet.
Air onto the refrigeration unit should not exceed 25°C.
Do not cover any ventilation holes on the front and back of the freezer.
Ensure there is always at least a 200mm gap above the cabinet, and when
installing a TMEF1500 (3 door) cabinet a 100mm gap behind the cabinet
(see below). Keep the ventilation slots at the top of the cabinet clear at all
times, never store cardboard cartons or other objects on top of the freezer.
Shelves
Shelves may be positioned at different heights to suit various products.
Always ensure that the shelf clips are securely engaged in each of the shelf
support strips. Support strips are marked ‘+’ for easy location of shelf clips.

2Operation
Automatic Start-Up
After the cabinet has been positioned in a suitable place, plug it in and check
the following activity.
Loading Product
Let the freezer run 30 minutes before loading it with product the first
time.
Allow adequate air space around each item to ensure even cooling and
efficient operation of the chiller.
Do not exceed a maximum load of 20kg per shelf.
Leave airspace of at least 75mm (3”) above the product on the top shelf.
Do not cover air outlet at the bottom of the cabinet with product as this
may cause spot freezing of products and other products to be warm.
Remove some product if the shelves are flexing.
Do not let anything overhang the shelves because this might stop the
doors from shutting or even break something.
Item Activity
Condenser Fan The condenser fan runs continuously throughout all
operations of the machine.
Lighting The sign and interior lights turn on and stabilise after a few
flickers.
Electronic
Controller
An electronic controller runs the chiller and is visible
behind the front panel. The display panel first shows - - -
before stabilising on the cabinet temperature.
Compressor
The compressor starts about one minute after the lights go
on. The compressor should switch off when the cabinet
internal air reaches the preset ‘set point’ temperature.
Evaporator Fan
The evaporator fan which circulates the cabinet air will not
operate until the defrost probe senses a temperature of
-8°C. On initial start up the fan should come on after a
delay of approximately four minutes (verified by air blowing
out of the bottom duct and the green LED.

Operation
User Manual
Operation The operation of this cabinet is controlled by a pre-programmed
microprocessor. The Microprocessor display indicates the temperature of
the cabinet ambient probe, except during a defrost where the temperature
of the cabinet probe is locked in, and during an alarm condition.
The display also has LED indicators showing the activation of the
compressor, the fan and the defrost. At alarm activation, the display
indicates the type of alarm signal; and an audible alarm sounds. The alarm
can be muted at the controller.
Controller
Components
A controlling probe located in a thermal mass inside the evaporator box,
called a ‘Cabinet Ambient Probe’.
An evaporator probe located within the evaporator coil, referred to as a
‘Defrost Probe’.
Defrost The first defrost will occur in 6 hours. During a defrost cycle (indicated by the
green defrost LED on the control panel) the compressor and the evaporator
fan will switch off. Four elements inside the evaporator box will then melt
away any ice build up. The duration of a defrost cycle depends on the
quantity of ice build up (usually about 10 minutes). A maximum of 22
minutes is preset. Defrost cycles are pre-programmed at 6 hour intervals.
During and after each defrost, the display will read the temperature detected
before the defrost cycle. The display will then show the return air
temperatures as the machine cycles during normal operation.
Defrosts should occur during off-peak periods to maximise the efficiency of
the machine. This can be achieved by switching the power off, then on
again, so that the subsequent 6 hourly cycle defrosts will not coincide with
peak periods.
Note:
A power cut would reset the defrost cycles.
This freezer has an over temperature cut-out inside the refrigeration unit
evaporator box. This is to safe guard the possibility of the defrost
elements remaining on under fault conditions (set at 55°C).
The light which illuminates the cabinet interior is permanently on, where
applicable.
Ensure the door gaskets form a good seal with the cabinet.
